Title: Improvements in apparatus for automatically feeding a lubricating oil to the cylinders of internal combustion engines
IPC: F16N7/32
Filed: 1935-11-11
Abstract: 450,290. Lubricating internal - combustion engine cylinders. CLEMENTSON, J. F. J., 7, Skeppsbron, Malmo, and CLEMENTSON, C., and CLEMENTSON, S., (trading as CLEMENTSON, C. & S.), 50, Kalksbrothsgatan, Limhamm, Malmo, Sweden. Nov. 11, 1935, No. 31152. [Class 12 (iii)] In apparatus for feeding oil to the cylinders of an internal-combustion engine in large quantities when starting and in smaller quantities when the engine is running, the supply of oil from a container 10<a> to a mixing chamber 11 is regulated by a rotatable valve 9 controlled by the vacuum in the intake manifold 17. The valve rod 8 has a bifurcated arm 7 movable by a pin 6 on a slidable rod 4 one end of which is connected to a bellows 1. A spring 2 holds the bellows expanded with the valve 9 fully open. The intake manifold is connected to the bellows 1 by a pipe 27, a valve chamber 28, and a pipe 33, and to the mixing chamber 11 by a pipe 16. Adjustable air valves 13, 22, lead to ducts 14, 15, connected to the mixing chamber 11. Superimposed on the valve 22 is a hinged valve 23 controlled by a cam 25<a> on a sleeve 25 adjustable on the rod 4. The chamber 28 contains a valve 32 which is urged towards closing position by a spring 34 and which can be opened by a thermostatic element 37. Upon starting up the valve 9 is fully open, the valve 23 is closed, and the oil and air are drawn through the ducts 10<b>, 14, respectively and through the pipe 16 to the intake manifold 17. When the engine reaches its normal temperature the thermostatic element 37 opens the valve 32 and the vacuum in the intake manifold 17 acts on the bellows 1. The opening of the valve 9 is then varied by the vacuum. At high speeds, which correspond to a high vacuum the bellows 1 closes and the cam 25a opens the valve 23 to increase the quantity of air and permit a weaker oil mixture to pass to the engine cylinders. The bellows 1 may be replaced by a diaphragm or by a piston in a cylinder. A bimetallic spring or other thermostatic element may replace the bellows 37 and may be heated by the cylinder block or by the cylinder cooling water.

Abstract: 1,272,753. Screwing machines. W. L. PROCTOR. 30 Sept., 1969 [1 July, 1968], No. 31264/68. Heading B3N. A screwing machine comprises a die chaser 12, mounted on a rotary spindle 11, a yoke 13 for opening and closing the chaser, a workpiece 16 clamped in a pneumatically actuated vice 15 carried by a support 14, slidable on a bed 10, the support being connected to a bed portion 18 by a toggle 25, 17, actuated by a pneumatic piston assembly 19. A bar 20 fixed to support 14 slides through yoke 13, and carries a stop 21 for causing closing of the die segments, and an adjustable stop 22 which causes opening of the segments. In operation, with vice 15 open, and die head 12 closed, a valve 23 is actuated, thus causing the vice to close on the workpiece 16. A second valve 24 is actuated, air pressure is supplied to piston assembly 19, and support 14 is moved to the right Fig. 1. The workpiece enters the die head which controls the feed rate, the force applied by assembly 19 being now reduced due to the toggle action. When stop 22 strikes yoke 13, the die head opens and valve 24 is actuated, so that the air supply to assembly 19 is reversed, and support 14 is retracted. At the end of the stroke, stop 21 resets the die head, and valve 23 is de-actuated. In a modification, pneumatic pressure is removed from assembly 19 during the screwing operation by the addition of further valves, Figs. 3, 4 (not shown).

Abstract: 299,713. Anode Rubber Co., Ltd., (Assignees of Darby, C. L.). Oct. 28, 1927, [Convention date]. Coagulating.-Electric endosmose is employed in the removal of water from layers or articles of rubber or like substance formed from an aqueous dispersion. In one method a metal plate coated with rubber is connected as anode while immersed in mercury or an electrolyte; exposed parts of the plate not coated with rubber are coated with wax or other insulating composition. In another method the coated plate, connected as anode, is placed between two metal plates connected as cathodes. In the apparatus shown, a wire or strip 32 is passed through an insulating seal 33 of soft vulcanized rubber in the base of a tubular tank 30 connected as cathode and is thereby coated with rubber or like substance from a dispersion in the tank. The coated wire then passes through a vessel 35, connected as a cathode, containing a conductive liquid for dehydration, and then to a final drying chamber 39. The wire is connected to the generators B, E by brushes 34. The depositing voltage may be 20-60 and the drying voltage 20-110. In a modification the coated wire is passed for dehydration between pairs of rollers connected as cathodes instead of through a conductive liquid. The invention may be applied to the dehydration of coated fabrics.

Abstract: 755,312. Door-operating appliances; hinges. GENERAL MOTORS CORPORATION. Nov. 1, 1954 [Nov. 18, 1953], No. 31484/54. Classes 65 (1) and 65 (2). A hinged lid, for example of the luggage compartment of a car, is supported by a pair of spring-loaded hinges, each comprising a torsion rod connected to the movable hinge member and anchored by means engageable in any one of a plurality of notches to vary the stress in the rod. In the arrangement shown the springs are in the form of torsion rods; the lid 16 has fixed to it two members 20 of channelsection separately pivoted on pins 30 in respective box-like members 32 fixed inside the structure 12. Each member 32 has fixed to it a member 50 providing bearings for the torsion rods 26, 28 and having a flange 52 with a series of notches to receive a bent end 44 of the rod 28, whereby this rod is anchored; the rod 28 has a cranked portion 40 bearing against a double link 34 pivoted to the member 20, and is anchored at its other end to the other member 32 in the manner shown for the rod 28, so that it is stressed torsionally and thus exerts an upward force on the lid 16. The other end of the rod 28 is cranked in the manner shown for rod 26, and acts similarly on the other hinge member 20. By shifting the end 44 of one or each spring to a different notch in the respective flange 52 the total force exerted by the springs can be adjusted to a number of different values; the two springs may be of different strength to allow more variety of adjustment. Opening of the lid is limited by engagement of the hinge member 20 with a yoke 60, the upper edge of the link 34 then being against the pin 30.
